Description

Cyclone flush toilet Technical Field

[0001] The present invention relates to the technical field of toilets, and in particular to a swirl flush type toilet. Background Art

[0002] Currently, toilets are widely used, but existing models on the market suffer from incomplete flushing due to contamination and accumulation of dirt. Surface contamination often requires manual scrubbing or secondary flushing, which wastes water and easily promotes bacterial growth. Flush-down toilets without ring holes typically use counter-flush toilets. These flush-down toilets have jet holes positioned at the front, extending the distance to the secondary water channel and reducing water pressure, resulting in insufficient flushing power. For example, in the invention patented by announcement number CN215053629U, this type of counter-flush toilet is prone to overflowing from the ring surface due to excessive counter-flush water flow, causing sewage to come into contact with the human body and endangering human health. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a swirl flushing toilet, which effectively flushes the area between the ring and the pot body to prevent contamination.

[0004] To achieve this technical objective, the present invention adopts the following solution: a swirl flush toilet, comprising a toilet body, the interior of which is a pot body; an annular ring channel is provided on the toilet body, a water outlet is formed at the front end of the ring channel, and a conical ring-shaped guide groove is provided at the lower portion of the ring channel below the water outlet; below the ring channel is the pot body, which has a funnel-shaped structure and a cap head connected to the bottom of the pot body;

[0005] The connection position between the pot body and the hat head is at the same height on both sides, or is in a stepped shape; and / or an inclined spray hole is opened on the rear side wall of the pot body, and the spray hole is aligned with the bottom position of the hat head.

[0006] Furthermore, the connection position between the pot body and the hat head is a stepped structure with the left side higher and the right side lower or the right side higher and the left side lower. The curvature of the cross section of the front wall away from the water tank end at the connection position between the pot body and the hat head is less than π / 6. The change in the shape of the pot body outlet effectively prevents the water from rushing into the hat head from swirling back and splashing out.

[0007] Furthermore, the angle between the line connecting the center of the water outlet and the center of the cross section of the circle in the plane in which it is located and the axis of the toilet body is less than 60°. A circular cover is installed on the toilet body, and the user cannot see the water outlet when standing in front of the toilet, that is, the water outlet is hidden, thereby improving the aesthetics of the toilet product.

[0008] Furthermore, the top wall of the cap head is an arc-shaped surface with a curvature ranging from π / 4 to π / 2. Compared to the traditional, nearly linear cap head, this solution increases the curvature of the cap head and reduces the pipe diameter of the cap head. When the cap head is filled with water, the pressure creates a siphon effect within the cap head, and the large arc top surface also generates a flushing effect, giving the cap head a dual function of siphoning and flushing, significantly improving sewage drainage efficiency.

[0009] Furthermore, the connection position between the pot body and the hat head is at the same height on the left and right. The toilet body also includes a main water channel and a secondary water channel. A water inlet is provided at the rear of the toilet body. Below the water inlet is the rear part of the main water channel, and the front part of the main water channel is connected to the circle channel and the secondary water channel respectively.

[0010] Furthermore, there is a cavity in the circle on one side of the water outlet, and the cavity is the main water channel; the circle on the other side of the water outlet is a blocking structure. This design can increase the water pressure at the water outlet, which is conducive to flushing.

[0011] Furthermore, the injection hole is an elliptical hole, that is, it is longer on the left and right and shorter on the top and bottom. The left and right water outlet widths are consistent with the width of the water seal surface, which increases the surface area of ​​the water seal covering the product and is conducive to the passage of the medium.

[0012] Furthermore, a water retaining edge is provided on the outer side of the water outlet to block the water flow from the flushing hole and prevent the water from overflowing due to excessive water flow. The connection between the water retaining edge and the ring channel is designed with a rounded corner, and the angle of the rounded corner ranges from 55° to 70°.

[0013] Furthermore, it also includes a sewage pipe, the rear end of the hat head is connected to the sewage pipe, and the diameter of the sewage pipe is less than or equal to 65 mm.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The toilet provided by the present invention is designed with a water outlet at the front of the ring channel. Water flows through the ring channel and rushes out from the water outlet, washing the pot body along the guide groove, forming a rotating flushing, and mixing with the water flow rushed in from the injection hole set on the side wall of the pot body, to achieve flushing of the guide groove, pot body and cap head, solving the problem of contamination formed at the pot body and the ring channel position of the existing toilet;

[0016] (2) The present invention also adopts another method to set the inner wall of the connection position between the pot body and the hat head to be high on the left (or right) side and low on the opposite side. The high side is extended together with the inner wall of the volute-type pot body, and the low side is the water inlet position of the pot body to the hat head. Through this height difference, the rotating water flow in the pot body can smoothly enter the hat head, discharge the dirt, and avoid the water flow in the pot body from swinging left and right and overflowing; the stepped connection structure is combined with the inclined spray hole to achieve a more prominent effect.

[0017] (3) The conical annular guide groove of the present invention is smoothly connected to the volute-type pot body, so that the water flows smoothly into the cap head along the inner wall of the spiral pot body, reducing water flow collision. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments, but the present invention is not limited thereto.

[0027] The present invention provides a swirl flushing toilet, comprising a toilet body 1, wherein the toilet body 1 comprises an upper panel, a ring channel 2, a pot body 3, a cap head 5, a sewage pipe 10, etc. The ring channel 2 is located at the upper part of the toilet body 1 and is connected to the upper panel of the toilet body 1. The lower edge of the ring channel 2 is connected to a conical ring-shaped guide groove 9, and the lower edge of the guide groove 9 is connected to the pot body 3 to form a smooth conical arc surface. The ring channel 2 is an annular structure, and a water outlet 4 is provided on the side wall of the ring channel 2 near the inner cavity of the toilet body 1. The water flowing out of the water outlet 1 flushes the pot body 3 along the guide groove 9, forming a rotary flushing. A water retaining edge 41 is provided on the outside of the water outlet hole 4. The water retaining edge 41 can prevent the excessive water flow from the flushing hole from causing some water to overflow, thereby solving the problem of product splashing and facilitating the control of the flushing angle of the product. Preferably, the connection between the water retaining edge 41 and the ring channel 2 is designed with a rounded corner, and the angle range of the rounded corner is between 55° and 70°.

[0028] The pot body 3 is a funnel-shaped structure, which is conducive to water flushing downward and increasing the water flow speed; a cap head 5 is provided at the bottom of the pot body 3, and the cap head 5 is connected to the sewage pipe 10. Preferably, the diameter of the sewage pipe 10 is less than or equal to 65 mm. Example 1:

[0029] As shown in Figures 1 to 4 (in order to better show the curvature changes of the product, the actual object scanning lines are displayed in the form of dotted lines inside), the angle θ between the line connecting the center of the water outlet 4 and the center of the circle 2 on the horizontal plane where they are located and the symmetry axis of the toilet on the horizontal plane where the center of the water outlet 4 is located is less than 60°; after installing the toilet ring cover, since the inner diameter of the cover is smaller than the inner diameter of the upper panel of the toilet body, the water outlet 4 is blocked and hidden by the cover, and the user standing in front of the toilet cannot see the water outlet 4, thereby improving the aesthetics of the toilet product.

[0030] The pot body 3 has a funnel-shaped inner wall volute structure. The initial point of the volute spiral seamlessly connects with the diversion groove 9, and the end point of the spiral is the connection point between the pot body 3 and the cap head 5. The connection point between the pot body 3 and the cap head 5 is a stepped structure, with the left side higher and the right side lower, or the right side higher and the left side lower. This connection point is the outlet of the pot body 3. The inner wall of the pot body 3 is at different heights on either side of the outlet. When the toilet is viewed in its normal use orientation, the left or right side of the pot body outlet is higher than the opposite side, creating a different rotational drop. This ensures that the water flows smoothly into the cap head 5, carrying waste, and avoids the phenomenon of water rotating without sinking or swaying from side to side within the pot body 3. In Figure 3, the left side of the outlet 31 is higher than the right side of the outlet 32. In some preferred embodiments, the front wall 6 of the pot body outlet is a curved surface. The curvature of the cross-section of this curved surface is less than π / 6. Unlike the large circular surface of the original swirl flush toilet, this curved surface is close to a vertical plane, effectively preventing water from flowing from the pot body 3 into the cap head 5 from back-spinning and splashing. In this embodiment, the injection hole is omitted, which can effectively reduce the occurrence of splashing and overflowing.

[0031] The top of the hat head 7 presents a curved surface structure with a large curvature from the perspective of Figure 3, and the specific curvature is preferably in the range of π / 4~π / 2. The top of the traditional hat head is an approximately flat structure, and the curvature is significantly smaller than the curvature of the top 7 of the hat head of this solution; the pipe diameter of the hat head 5 is much smaller than the discharge outlet of a traditional toilet. Therefore, when the hat head is filled with water, a siphon phenomenon is generated in the hat head due to the pressure, and the large curved top surface can also produce a flushing phenomenon, so that the hat head 5 has both siphoning and flushing dual functions, which significantly improves the sewage discharge effect.

[0032] When in use, the water in the water tank flows along the circle channel 2 to the water outlet 4, rushes out obliquely from the water outlet 4, rotates through the guide groove 9 to flush the pot body 3, and reaches the outlet at the bottom of the pot body. Since the inner wall of the pot body outlet is high on one side and low on the other side, a spiral channel inclined toward the cap head 5 is formed, and the water flows smoothly into the cap head 5, solving the problem of the water flow not rotating downward. Example 2:

[0033] As shown in Figures 5 and 6, when the connection position of the pot body 3 and the hat head 5 is at the same height on the left and right, a main water channel 11 and a secondary water channel 13 are set in the toilet body 1, and there is a cavity in the circle channel 2 on one side of the water outlet 4, and the cavity is the main water channel 11; the circle channel 2 on the other side of the water outlet 4 is a sealing structure without a cavity. This design can increase the water pressure at the water outlet 4, which is conducive to flushing.

[0034] A water inlet 8 is provided at the upper rear portion of the toilet body 1, and the water inlet 8 is provided at the upper rear portion of the main water channel 11. A secondary water channel 13 is formed between the toilet body 1 and the upper portion of the pot body 3, and the front portion of the main water channel 11 is connected to the ring channel 2 and the secondary water channel 13, respectively. An inclined spray hole 12 is provided on the side wall of the pot body where the secondary water channel 13 is located, changing the position of the original spray hole. The inclination angle of the spray hole 12 satisfies the requirement that the water flow ejected from the spray hole 12 is aligned with the bottom position of the cap head 5 for flushing. Preferably, the spray hole 12 is a flat elliptical hole, i.e., longer on the left and right and shorter on the top and bottom. The left and right water outlet width is consistent with the width of the water seal surface, which increases the surface area of ​​the water seal covering the product and facilitates the passage of the medium.

[0035] During use, water flows into the main water channel 11 from the water inlet hole 8, and then splits into two streams. One stream passes through the circle channel 2, rushes out from the water outlet hole 4 at the front end of the circle channel 2, and rotates through the guide groove 9 to flush the pot body; the other stream flows through the secondary water channel 13 and rushes out from the injection hole 12 to enter the cap head 5. The two streams of water mix and flush, realizing the flushing of the guide groove 9, the pot body 3 and the cap head 5, solving the problem of contamination of the existing toilet at the position of the pot body 3 and the circle channel 2. Example 3:

[0036] Combining Example 1 with Example 2, the connection position between the pot body 3 and the hat head 5 is a stepped structure with the left or right side higher than the opposite side, and an inclined spray hole 12 is opened on the rear side wall of the pot body 3, and the spray hole 12 is aligned with the bottom position of the hat head 5.

[0037] The advantages of the present invention over other existing flush toilets are:

[0038] (1) Easy to clean: Existing toilets are generally ring-hole or counter-punch products, which easily form dirt at the hole position and are difficult to clean. The present invention is a rotary flush toilet with a funnel-shaped pot body that is easy to scrub.

[0039] (2) Good visual effect: There is dirt at the ring hole of the existing toilet, which is difficult for people to accept after long-term use. However, the water outlet of the present invention is located at the front of the product, which cannot be detected visually, and has a water retaining edge, which cannot be found.

[0040] (3) The diameter of the product pipe is smaller than that of ordinary flush toilets: when the water flows through the funnel-shaped pot body, it is accelerated and flows downward from the cap head. Due to the fast flow rate, the pipe is easily filled, which can temporarily form a siphon effect and speed up the discharge of waste.

[0041] (4) The problems of unclean flushing and overflow are solved by using the spray hole and / or the stepped pot body and the cap head connection structure.

[0042] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art may make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered to be within the scope of protection of the present invention.
